ABSTRACT:
A method and system for train inauguration over an internet protocol (IP) based communication network. The present invention describes a method of train inauguration that includes identifying a leading car of a plurality of cars that form a train. The train includes at least one unit of cars such that a first unit includes the leading car. Network and configuration information is discovered for cars in the train using a discovery protocol. The network and configuration information is broadcast to units in the train. Car and unit topology of the train is generated based on the network and configuration information and the leading car that is identified. NAT translation addresses are generated for fixed IP addresses of devices in the plurality of cars. Routing information is exchanged between routers to enable communication between devices in the train using the NAT translation addresses.
